Overview

About

Maintained by Gábor CsárdiCRAN page ↗GitHub ↗Issues ↗Declared funder: Posit Software, PBC

Compress and decompress data with the 'Zstandard' algorithm https://facebook.github.io/zstd/, a fast lossless compression format. Works on raw vectors in memory and on files, and can create and extract 'zstd' compressed 'tar' archives. Supports compression levels, multithreaded compression, long distance matching, content checksums, and training dictionaries for better compression of small, similar inputs.
